Nokia patents self-charging Graphene based Photon-Battery that can be printed on flexible substrates

We keep on reporting Nokia innovations regularly and some of them can truly revolutionize the way, in which things around us work. The innovation, that we are covering today is perhaps one of these, with truly revolutionary potential.

Nokia is one of the leaders in Graphene based research work and we just reported Nokia prototyping optical sensor based on Graphene. Now, think about a totally different use of Graphene and Nokia has just patented a Self-charging Graphene based Photon-Battery. Yes, you heard it right, self-recharging battery resulting in an energy-autonomous device.

The generation of protons is facilitated by the presence of water. The configuration of the GO electrode with the water and the higher pH media renders the battery 300 a dynamic battery. In other words, the battery 300 is capable of regenerating itself immediately after discharge through continuous chemical reactions. In particular, the battery 300 may be automatically charged back to open circuit voltage without an external energy input. The result is a low-power, energy-autonomous device.

Another great aspect of this invention lies in the fact that the Battery may use humid air to recharge itself.

During operation, the battery 300 can generate an open circuit voltage on the order of about 1 volt (V) when in the presence of humid air (for example, when the relative humidity is about 30%). The battery 300 also exhibits a fast recovery of its voltage within a few minutes after being fully discharged and without the application of external energy.

Much more amazing is the fact that it even can be printed on flexible substrates for making a flexible battery or can be made highly transparent.

The battery 300 can be made flexible using printing technology. For example, the battery 300 can be printed onto a flexible substrate. The battery 300 can also be made to have highly transparent optical properties or elastomeric properties.
